CORE DEFINITION

Rapid Application Development, emphasizing rapid delivery of usable software through prototype iteration, component reuse, and close user involvement.

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

Speed-first development strategy. When requirements are uncertain, obtain feedback through rapid prototypes to reduce development risk.

anchor

Anchor fast decisions

When requirements are uncertain, traditional waterfall has high risk. RAD uses rapid prototypes + component reuse + close user involvement, delivering a usable version first and then iterating, using early feedback to correct direction, shortening the cycle from 'idea to usable', reducing the risk of requirement mismatch.

Sherlocking

Sherlocking refers to the phenomenon where a platform owner copies the features of a third-party developer's app and integrates them into the platform, thereby rendering the third-party app obsolete. The term originates from Apple's Sherlock search tool, which was introduced in Mac OS 8.5 and later incorporated features similar to those of third-party search utilities like Watson, leading to the coining of the term.

Beat Frequency

The term "beat note" or "beat frequency" originates from acoustics, referring to the interference of two sound waves with similar but different frequencies. The resulting interference signal has a frequency equal to the absolute difference between the two original frequencies, hence the name. This concept is also applied in optics and electronics, where combining two signals of different frequencies yields a new signal with a frequency equal to their difference. For example, consider two sine waves with equal amplitude, no phase difference, but slightly different frequencies.
